To all whom it may concern/.-

Be it known that we, DANIEL B. BADGER,

of Winchester, in the county of Middlesex,

g1 a For the details of the invention reference may be had to the following specification and drawings accompanying the same, in which-' Figure 1 represents a front elevation,

' partly broken away and in section, of a window constructed in. accordance with our in ventiou, showing one side of the frame and sashes of the window.- Figs. 2 and 3 represent, respectively, a vertical section and a horizontal section of the same, taken on lines 2 2 and 3 3 of Fig. 1 Figs. 4 and 5 represent detail perspective views of portions of the top and bottom rails of the window-sash. Fig. 6 represents a cross-section. on line 6 6 of Fig. 1, showing the bottom sash in section.

Fig. 9 re resents a fragmentary elevation of the Si e railof one of the sashes. Fig. 10 represents a longitudinal section taken through the cross-rail of the sash, showing a different construction. Fig. 11 represents a cross-section on line 11 11 of Fig. 10. Fig. 12 represents a fra ment-ary perspective view of one end of the ongitudi- 45 nal webs of this form of sash. Fig. 13 represents a similar view showing the same in place in the sash. Fig. 14 represents a crosssection on line 14 14""of Fig. 11. 1 The same reference characters indicate the same arts in all the figures.

Re erringto the draw1ngs,-1 designates the window-framaand 2 and 3 the lower and upper sashes, respectivel bothiframe and, sashes being made of s eet .metalbent-into form and the pane of the sash preferably com: posed of wire-glass.

The sashes are composed of side rails 4 constructed of a body-strip 5 of sheet metal, having a groove for receiving the pane 7, and

an outer strip 8, connected at its edges tothe.

two edges of the body-strip 5, as shown in the patent hereinbefore referred to, except that the. joint, instead of being made by doubling the edge of the body-strip 5 back on itself and then outwardly, is made by simply turning backithe edges of the body-strip once and forming a double bend on the edges of the outer strip to form interlocking lips, as shown in Fig. 3. The top and bottom rails 16. 17 of the sashes are constructed substantially the same as are the correspondin parts of the patent referred to, as are also t e rails 22, 23-, and 31 of the frame, for a fuller description of which reference may be had to the said patent. The essential features of the present invention consist in the construction of the cross-rails/ 10 of the sashes and in the means by which said cross-rails are rigidly and securely as Well as detachably connected to the exterior rails forming the frames of the sashes. -Eachcross-rail 10 is constructed of two stri s 11 11, which are located side by side wit their ed es in contact, such edges.

being each folded Jack upon itself, so as to form lips or guides 12 13, which are engaged and locked together, this forming a co nstruction in which the edges of the strips are folded together and interlocked. The intermediate 1 ortions of the strips are bent outwardly from the'folds andseparated from each other, being-bent sharply inward or indented longi tudinally at their central portions to form grooves 14 forreceivingthe panes. 7, the inwardly-bent portions of the strips formin also, in the interior of the rail, ridges 15, whic separate the interibr of the rail into two longitudinalpas sagesw 19-. b Within the cross rail locatedbetween the ribs 15 and extending acrbss from, one edge to the other of the stnt'ips its edges being in contact with the fol ed portions 12 13, is a late or web 20, which runs longitudinally o the rail almost from one end to the other and serves to stiffen the same and retain it in shape.

The cro ss-rail'is detachably and firmly nected to the top and bottom rails16 17 by means of projecting members or tongues 21 24, arranged in pairs side by side 'and-p"?ject .andri from the top and bottom rails, respectively. These to ues are shaped in cross-section to correspon with the passages 18 19, being separated from each other by a distance equal to the width of the ribs 15, so that they are adapted to extend into the ends of the crossrail and fit closely therein. The tongues 24 are rigidly connected together by webs 25 26 'dly connected to the bottom rail, while t e members 21 may be independent of each other and separately connected to the body-strips- 16 16 of the top rail. As described in our prion patent, these body-strips of the top rail are separated from each other at their lower side by a slot 27 of width sufiicient to permit insertionof the pane and are connected together by'a slide or cover 28, which forms the upper face of the rail. This cover being of sheet metal is flexible, so that the body-strips, and with them the ton es 2'1,;aye movable toward and from each t er, 'the distance between them being regulated by a clampi -screw29, the shank-of which passes through a hole in the web of one of the tongues 21 and is threaded into the other tongue. When the parts are assembled, the

clamping-screw 29 is adjusted to draw the body strips together,

and thereby the tongues 21 are caused to clamp tightly on opposite sides of theinternal ribs in the'cross-rail, thereby securely holding the cross-rail in frictional connection with the top rail. This construction, however, is not essential, as the projections 21 may be, if desired, joined integ'rally together in the same manner as are .the tongues 24=by stiffening webs or flanges similar in all respects to the webs 25 26, which unite the members 24 and hold them at an invariable distance apart.

A j window-sash constructed as hereinbefore described will have the maximum of i strength and rigidity Withaminimum weight,

as is evident, proof.

The pulley 36, overwhicn the sash-supporting weight chain or cord 37 passes, is sacured in a novel manner. The pulley itself is pivoted at 38-to sheet-metal wings 39, between which it is located and the weight-' chain is guided, and the wings being connected to and rojec'ting outward from the sides of a face-p ate 40. The. plate 40 and wings 39 constitute a pulley-holding frame. Openings of sufficient wi' th to admit insertion. of the pulleys and platesand of substantially the same size as said plates aremade in the walls-41 of :the side rails 22 of the windowframe in the sash-guides, and 'to these'walls on the interior-of the frame-rails are secured, rigidmetal plates 42, preferably castings.

esides being absolutely fire These plates are riveted to the walls 41 and extend over the pulley-receiving openings therein, being provided with registering openin s 43, through which the pulleys and pressed webs 44 to engage the ends of the face-plates 40. The latter are detachably secured to lates 42 by screws 45. Thus a structure of a sheetmetal Window-frame to which sash-pulleys are detachably secured. and which has sufficient strength at the points of attachment thereof to support the weight of the sashes is secured.

The weight-chain 37 is attached to the side rail of a sash by means'of a hanger 48, having an eye 19, to which the chain or cord is attached, and also having lateral projections 50 50, which form locking-bars. Preferably the hanger is constructed of wire bent so that its middle part forms the eye and its ends the lockingbars, and the latter are offset from the plane of the eye, so as to extend into the interior of the rai the eye and main portion of the hanger being contained in the channel between the window-frame and the strip 8 of the rail. A keyhole-shaped opening 51 is tachment of the hanger'therefmm, the detachment being effected by turning the hanger until the eye extends horizontally and the locking-bars are vertical and then slippin one of the bars through the opening.

be readilywithd-rawn.

In the form of window illustrated in Fi s. 10 to 14 there is substituted in place of t e web'20 one or more lates or webs 52, extending longitudinally oi other thereof in order to perform the stiflenare formed projecting fingers 53, w 'ch extend'beyond the ends ofthe cross-rail and are adapted totproject through slots 54 in the top and bottom railson each side ,of the flanges '55 56, which are turned back to form the in dented portions of these rails, which constitute thepane-reeeiving grooves of the rails. Cross-pieces .5,7 58 are placed in the u per and lower rails, respectively, extendin om 55 56,;andfthe ends of the fingers are folded or lapped over the outer edges of'thecrosspiec es, thereby retaining them in the osition above described "and tying the top, ottom, and cross'rails together, thereby making a strong construction which holds the parts to gather, so that the panes of glass are firmly bound in place even when the window is so greatly heated that the rails become distorted s andsag. Without this construction the bot- -fteiiitrailofsthe sash when heated by a fire in the building whereinv the window is :placed of the glass to sag down, separating thetops of the panes from the upper rail, so that a stream of water striking them would knock them out'of place, leaving the window unprotected. This objectionable result is pre- 9 prcje'ct, and haying ofi set' or de vented in-our infventinnby reason 'of the fact After t is has been done the other bar may ing function of the web 20. On the lates, 52

would becaused by itsown weight and that formed in the strip 8 of the rail to permit de the cross-rail 1-0 andalso being preferably carried from one side to the side to side thereof inconta'ct withthe anges that the webs and cross-pieces, with the crossrail, make a truss which hold's the top and bottom rails at an invariable distance apart under all conditions, so that displacement of the panes is impossible. Obviously the webs may be secured to the cross-pieces in other ways than that shown, as by being riveted.

In the drawings there are shown two plates 52 placed side by side, their respective fin gers being located on opposite sides of the cross-pieces 57; but it is obvious that, if desired, only one of such plates may be provided and that the cross-pieces may be securely held thereby. Also, instead of having Webs 52 extending entirely across the rail 10 from side to side of the sash, the fingers 53 may be simply the ends of narrow strips extending the length of the cross-rail, but entirely separate from each other. With this construction, however, less lateral stiffness is imparted to the cross-rail by these strips:

thanis the case when they are connected and occupy the entire width of the rail.

The cross-pieces may have formed upon their ends flanges 59 60 projecting perpendicularly from the body portions of the crosspieces and in opposite directions, which flanges are adapted to bear against the side plates of the exterior rails of the sash and cooperate in giving stiffness to the sash.
